Worst day in 10 months as Wall Street reacts to Brexit

The S&P 500 turned negative for the year-to-date on Friday as Wall Street suffered its largest selloff in 10 months after Britain's decision to leave the European Union caught traders wrong-footed.

In the busiest trading volume for a single session in nearly five years, financial stocks led the decline on the S&P 500 with a 5.4 percent drop -the largest for the sector since November 2011. - Referenced Article
